[PATCH] drm/nouveau: add config NvForceGpioReset
Some OEMs manage to mess up their VBIOS such that GPIO isn't initialized
correctly at boot time. The NVIDIA proprietary driver seems to initialize
GPIO unconditionally at boot. Nouveau doesn't because it assumes GPIO is
set up correctly. This patch adds a new config option, NvForceGpio, which
allow users with broken VBIOS to force a GPIO reset at boot time. This
issue seems to be rare enough to not warrant a DMI override.
